Can't install Version 8 due to having installed 9 on macOS

Hi there,
I accidentally downloaded the latest version and installed it. When I realized my pro license is for version 8, I uninstalled it and installed that instead. As with many others, I got the Database error:


Every other topic I’ve seen on this for the windows version. I would like to locate the database so I can delete it and install em Client v8.

I’m using macOS Monterey 12.4.

Thank you and have a nice day.

I just found a solution via a generic ‘how to remove leftovers’ tutorial.

You have to Right Click on Finder>Go to folder>~/Library/Application Support/eM Client

I deleted that folder and re-installed and it opened.
I had tried finding this folder before but it didn’t show up in any of the Library folders I accessed, so that’s that.

Thank you and I hope this helps somebody in the future.


Yes, this is because the database was used by a new version of eM Client, version 9.

It is not backwards compatible with 8, so you need to remove the database /Users/yourusername/Library/Application Support/eM Client/ if you want to use 8.
